To reproduce:
1. Throw 2 shapes on a new logic diagram
2. Connect them with a line connector
3. Select connection and go to Edit->Add Bookmark (i.e. create a bookmark for the connection). Now you should see a small blue rectangular decoration on top of the connection.
4. Grab one of the ends of the connection and drag it on the top of the bookmark decoration
Result: Application hangs.
Expected: application should be working normally and a "no-smoking" cursor should be appearing.

Problem: Decoration's figure is registered with the connection's edit part, hence when you hover on it the target edit part is connection's edit part. However, connection cannot be connected to itself that results in an infinite loop. Hence, we shouldn't be getting connection edit part as a target edit part when we reconnect it.
